Abstract
Cancer presents high mortality and morbidity globally, largely due to its complex and heterogenous nature, and lack of biomarkers for early diagnosis. A proteomics study of cancer aims to identify and characterize functional proteins that drive the transformation of malignancy, and to discover biomarkers to detect early-stage cancer, predict prognosis, determine therapy efficacy, identify novel drug targets, and ultimately develop personalized medicine. The various sources of human samples such as cell lines, tissues, and plasma/serum are probed by a plethora of proteomics tools to discover novel biomarkers and elucidate mechanisms of tumorigenesis. Innovative proteomics technologies and strategies have been designed for protein identification, quantitation, fractionation, and enrichment to delve deeper into the oncoproteome. In addition, there is the need for high-throughput methods for biomarker validation, and integration of the various platforms of oncoproteome data to fully comprehend cancer biology.

Abstract
Mutations in the genome of a normal cell can affect the function of its many genes and pathways. These alterations could eventually transform the cell from a normal to a malignant state by allowing an uncontrolled proliferation of the cell and formation of a cancer tumor. Each tumor in an individual patient can have hundreds of mutated genes and perturbed pathways. Cancers clinically presenting as the same type or subtype could potentially be very different at the molecular level and thus behave differently in response to therapy. The challenge is to distinguish the key mutations driving the cancer from the background of mutational noise and find ways to effectively target them. The promise is that such a molecular approach to classifying cancer will lead to better diagnostic, prognostic and personalized treatment strategies. This article provides an overview of advances in the molecular characterization of cancers and their applications in therapy.

Abstract
The quest to decipher protein alterations in cancer has spanned well over half a century. The vast dynamic range of protein abundance coupled with a plethora of isoforms and disease heterogeneity have been formidable challenges. Progress in cancer proteomics has substantially paralleled technological developments. Advances in analytical techniques and the implementation of strategies to de-complex the proteome into manageable components have allowed proteins across a wide dynamic range to be explored. The massive amounts of data that can currently be collected through proteomics allow the near-complete definition of cancer subproteomes, which reveals the alterations in signalling and developmental pathways. This allows the discovery of predictive biomarkers and the annotation of the cancer genome based on proteomic findings. There remains a considerable need for infrastructure development and the organized collaborative efforts to efficiently mine the cancer proteome.

Abstract
Background When comparing myelogenous blasts from bone marrow and peripheral blood, immunophenotyping usually show a strong correlation of expression of surface antigens. However, it remains to be determined, whether this correlation also exists on the level of protein expression. Method Therefore, we investigated both bone marrow and peripheral blood blast cells from six patients with newly diagnosed acute myeloid leukemia (AML) using conventional two-dimensional electrophoresis in the first dimension and linear polyacrylamide gels (12%) in the second dimension. Proteins were visualized using the silver staining method and image analysis was performed using the PDQuest system. Results For each patient over 80 proteins were evaluated in the sample from peripheral blood and bone marrow. We could demonstrate that the protein expression profile of bone marrow did not significantly differ from the expression patterns of peripheral blast cells. Conclusion The proteome-set of leukemic blast cells from marrow and blood, does not differ substantially when drawn from AML patients with over 80 percent blast cells in both compartments. This indicates that in AML, blasts from peripheral blood samples can be considered suitable for investigations of the proteome using 2D-electrophoresis.

Abstract
Acute myeloid leukemia (AML) is a frequent hematological malignancy. Despite enormous therapeutic efforts that range from various cytotoxic agents to allogeneic stem cell transplantation, overall survival of patients with AML remains unsatisfying. The poor survival rates are mainly due to therapy-related mortality, failure of induction chemotherapy and early relapses. Therefore, novel therapeutic agents that are more efficient and better tolerated are eagerly sought after. For existing therapeutic strategies, there is a lack of markers that are capable of reliably predicting prognosis or the therapeutic response prior to treatment. There is hope that elucidation of the AML-specific proteome will prompt the discovery of novel therapeutic targets and biomarkers in AML. Modern mass-spectrometry instrumentation has achieved excellent performance in terms of sensitivity, resolution and mass accuracy; however, so far, the contribution of proteomics to the care of patients with AML is virtually zero. This might be partly because mass spectrometry instrumentation and protein fractionation still lack true high-throughput capabilities with highest levels of reproducibility, thus hampering large-scale translational studies with clinical samples. Since mass-spectrometry instruments are very intricate devices, their successful operation will hinge on the willingness and ability of mass-spectrometry experts and clinical researchers to adopt new views, learn from each other and cooperate in order to ultimately benefit the patient suffering from AML. This review highlights some clinical problems circumventing the treatment of patients with AML. Furthermore, it provides a brief overview of the technical background of standard proteomics approaches and describes opportunities, challenges and pitfalls of proteomic studies with regards to AML.

Abstract
The objective of this study was to explore the protein expression pattern in normal endometrial mucosa (n = 5) and endometrial carcinoma (n = 15) of low (diploid) and high (aneuploid) malignancy potential by two-dimensional gel electrophoresis (2-DE). The specimens were evaluated for histopathologic subtype, stage and grade in relation to DNA ploidy. A match-set consisting of five samples from normal endometrium, eight diploid and seven aneuploid tumours was created. All the diploid and three of the aneuploid tumours were of endometrioid subtype, while the remaining four were of uterine seropapillary type. There were 192 protein spots differentiating diploid tumours from normal endometrium and 238 protein spots were separating aneuploid tumours from normal endometrium (p < 0.01). A cluster analysis based on 52 significantly deviating protein spots within the groups showed clustering and separation of the normal endometrium, diploid and aneuploid tumours. In conclusion this study showed significant differences in protein expression between normal endometrium and endometrial carcinoma as well as between endometrial carcinoma of low and high malignancy potential. In future studies these results may provide useful in finding new sensitive prognostic markers for endometrial cancer.

Abstract
Advances in proteomics technology offer great promise in the understanding and treatment of the molecular basis of disease. The past decade of proteomics research, the study of dynamic protein expression, post-translational modifications, cellular and sub-cellular protein distribution, and protein-protein interactions, has culminated in the identification of many disease-related biomarkers and potential new drug targets. While proteomics remains the tool of choice for discovery research, new innovations in proteomic technology now offer the potential for proteomic profiling to become standard practice in the clinical laboratory. Indeed, protein profiles can serve as powerful diagnostic markers, and can predict treatment outcome in many diseases, in particular cancer. A number of technical obstacles remain before routine proteomic analysis can be achieved in the clinic; however the standardisation of methodologies and dissemination of proteomic data into publicly available databases is starting to overcome these hurdles. At present the most promising application for proteomics is in the screening of specific subsets of protein biomarkers for certain diseases, rather than large scale full protein profiling. Armed with these technologies the impending era of individualised patient-tailored therapy is imminent. This review summarises the advances in proteomics that has propelled us to this exciting age of clinical proteomics, and highlights the future work that is required for this to become a reality.

Abstract
Many leukemic oncogenes form as a consequence of gene fusions or mutation that result in the activation or overexpression of a tyrosine kinase. To identify commonalities and differences in the action of two such kinases, breakpoint cluster region (BCR)/ABL and TEL/PDGFRbeta, two-dimensional gel electrophoresis was employed to characterize their effects on the proteome. While both oncogenes affected expression of specific proteins, few common effects were observed. A number of proteins whose expression is altered by BCR/ABL, including gelsolin and stathmin, are related to cytoskeletal function whereas no such changes were seen in TEL/PDGFRbeta-transfected cells. Treatment of cells with the kinase inhibitor STI571 for 4-h reversed changes in expression of some of these cytoskeletal proteins. Correspondingly, BCR/ABL-transfected cells were less responsive to chemotactic and chemokinetic stimuli than non-transfected cells and TEL/PDGFRbeta-transfected Ba/F3 cells. Decreased motile response was reversed by a 16-h treatment with STI571. A phosphoprotein-specific gel stain was used to identify TEL/PDGFRbeta and BCR/ABL-mediated changes in the phosphoproteome. These included changes on Crkl, Ras-GAP-binding protein 1, and for BCR/ABL, cytoskeletal proteins such as tubulin, and Nedd5. Decreased phosphorylation of Rho-GTPase dissociation inhibitor (Rho GDI) was also observed in BCR/ABL-transfected cells. This results in the activation of the Rho pathway, and treatment of cells with Y27632, an inhibitor of Rho kinase, inhibited DNA synthesis in BCR/ABL-transfected Ba/F3 cells but not TEL/PDGFRbeta-expressing cells. Expression of a dominant-negative RhoA inhibited both DNA synthesis and transwell migration, demonstrating the significance of this pathway in BCR/ABL-mediated transformation.

Abstract
Although most drugs target proteins, the proteome has remained largely untapped for the discovery of drug targets. The sequencing of the human genome has had a tremendous impact on proteomics and has provided a framework for protein identification. There is currently substantial interest in implementing proteomics platforms for drug target discovery. Although the field is still in the early stages, current proteomic tools include a variety of technologies that could be implemented for large-scale protein expression analysis of cells and tissues, leading to discovery of novel drug targets. Proteomics uniquely allows delineation of global changes in protein expression patterns resulting from transcriptional and post-transcriptional control, post-translational modifications and shifts in proteins between different cellular compartments. Some of the current technologies for proteome profiling and the application of proteomics to the analysis of leukemias by our group are reviewed.

Abstract
The identification of coding sequences in a number of species, including human in the near future, has ushered in the post-genome era. In this era, technologies are becoming available that allow the profiling of tissues and cell populations at the genomic, transcriptomic and proteomic levels. The molecular analysis of tissues at all three levels has been referred to as operomics. This review covers some basic technologies for operomics and their application to some lymphoid disorders. It is proposed that no one type of analysis is fully informative and that information that can be derived from the different compartments encompassed in operomics is complementary. Prospects for introducing such profiling technologies into the clinical laboratory will depend on their robustness, their user friendliness and the clinical relevance of the added information they provide, which cannot be captured through other technologies in use in the clinical laboratory.

Abstract
The protein expression patterns of normal, metaplastic and malignant oesophageal tissues were analysed by two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) to identify changes associated with Barrett's metaplasia and transformation to oesophageal adenocarcinoma. Heat-shock protein 27 (Hsp27), a small heat-shock protein which is protective against cytotoxic stresses, was abundant in normal oesophagus. However, Hsp27 expression was markedly lower in Barrett's metaplasia and oesophageal adenocarcinomas. This was confirmed by immunohistochemical analysis. Hsp27 protein was most highly expressed in the upper layers of squamous epithelium and exhibited a pattern of expression that corresponded with the degree of squamous maturation. Northern and Southern analysis demonstrated Hsp27 to be regulated at the level of mRNA transcription or abundance. Normal oesophageal tissues were examined for gender differences in Hsp27 expression. Women expressed fourfold higher levels of Hsp27 mRNA, however, this difference was not appreciable in protein expression. Hsp27 protein was inducible by heat shock in Barrett's adenocarcinoma cell lines and an immortalized oesophageal epithelial cell line (HET-1A), but not by oestradiol. These results demonstrate abundant constitutive expression of the stress-response protein Hsp27 in the normal oesophagus, and suggest that low-level expression in Barrett's metaplasia may be one factor which may influence susceptibility to oesophageal adenocarcinoma development.

Abstract
We have utilized two-dimensional polyacrylamide gel electrophoresis (2-D PAGE) coupled with silver stain to identify cellular proteins in human non-Hodgkin's B-lymphoma (NHL). Five cell lines (SKDHL2B, WSU-DLCL2, WSU-NHL, WSU-FSCCL and SKLN1), representing four different NHL maturational stages and a normal Epstein-Barr virus (EBV)-transformed line of B-cell origin (SKLN1) were studied. The NHL lines were immunophenotyped using flow cytometry with lineage associated monoclonal antibodies. Whole cell lysates of the cell lines were subjected to 2-D PAGE analyses. The gels were analyzed with an image scanning computer and the qualitative differences of protein patterns were studied. Results revealed great similarities in patterns of the NHL lines. A master map containing common NHL-protein spots was constructed. When the map of each tumor line was compared to the master map, several protein spots were associated with each NHL-grade. Search for these proteins in the normal EBV-transformed B-cell line showed that only one of the proteins (S3; M(r)/pI 19/5.9) was present. Proteins that were detected in malignant NHL, but not in the normal EBV-line, could provide important information regarding the human NHL B-lymphocyte data-bases. Whether or not these proteins are definite malignant markers to distinguish between different NHL maturational stages needs further exploration through electroblotting and microsequencing.

Abstract
Two-dimensional polyacrylamide gel electrophoresis (2-D PAGE) was used to identify cellular proteins in T and B acute lymphoblastic leukemia (ALL) cell lines. Five lines, REH and BALL-1 of B-cell lineage, CCRF-CEM and HPB-ALL of T-cell lineage, and a normal Epstein-Barr virus (EBV)-transformed line of B-origin (SKLN1) were studied. The lines were immunophenotyped using flow cytometry and lineage associated monoclonal antibodies. Whole cell lysates of the cell lines were subjected to 2-D PAGE analyses. 2-D gels were analyzed with an image scanning computer and the qualitative as well as quantitative differences of the protein patterns were studied. Despite the great similarities in the patterns of the B- and T-gels, three proteins were unique to B-cell lines, while eight were unique to T-cell lines. Using cell lines is the first step toward identifying potential markers in ALL and can provide important information regarding the human ALL databases. Whether these proteins are definite markers for B- or T-ALL or are unique to the cell lines studied needs further exploration.

Abstract
The morphology, growth properties and cellular protein patterns from parent and two transformed C3H10T1/2 cell lines were analyzed to associate the phenotypic and protein differences with cell transformation. Transformed 10T1/2 cells were obtained by colony isolation after exposure of parent 10T1/2 cells to methylcholanthrene (MCA-1 cell line) or X-ray irradiation (XR-III cell line). Compared to parent 10T1/2 and MCA-1 cells, XR-III cells were much smaller in size and exhibited the highest growth rate, greatest cell saturation density, increased plating efficiency and greater expression of proliferating cell nuclear antigen. MCA-1 cells showed intermediate characteristics between parent and XR-III cells. Among the three cell lines, only XR-III cells showed anchorage-independent growth in soft agar. When [35S]methionine-labeled whole cell lysate proteins were separated by two-dimensional polyacrylamide gel electrophoresis, computer comparison algorithms revealed a 97% similarity in protein profiles among almost 800 proteins detected from each cell line. However, comparison of proteins patterns of the transformed cell lines to that of parent 10T1/2 cells showed that 30 and 20 proteins were induced or repressed in XR-III cells and MCA-1 cells, respectively. Similarly, 81 and 24 proteins showed significant quantitative changes (threefold or greater) in XR-III and MCA-1 cells, respectively, as compared with parent 10T1/2 cell proteins. The anchorage-independent growth and increased proliferation properties of XR-III cells suggest a later stage of transformation compared to MCA-1 cells.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
High resolution two-dimensional polyacrylamide gel electrophoresis (2-D PAGE) in combination with computer-assisted densitometry was used to analyze sequential changes in polypeptide expression during chemically (aflatoxin Bl; AFB), spontaneously, and oncogene (v-Ha-ras, v-raf, and v-raflv-myc)-induced experimental rat hepatocarcinogenesis. Two-dimensional mapping of [35S]methionine and [32P]orthophosphate-labeled whole cell lysate and nuclear polypeptides revealed subsets of polypeptides specific for each transformation modality in the in vitro rat liver epithelial (RLE) transformation model. Many of the observed changes in whole cell lysate preparations were localized to specific subcellular organelles. Significant alterations in the expression of the extracellular matrix protein, fibronectin, as well as tropomyosin- and intermediate filament-related polypeptides (vimentin, beta-tubulin, cytokeratins 8, 14, and 18, and actin) were observed among the various transformant cell lines. Whereas alterations in the tropomyosin isoforms appeared to be transformation specific, concomitant modulation of intermediate filament expression was related more to the differentiation state of the individual cell lines than to the transformed phenotype. To integrate protein and DNA information of polypeptides believed to be critically involved during cellular transformation, N-terminal amino acid microsequencing of selected nuclear polypeptides was performed. Preliminary results suggest that N-terminal blockage of rat liver epithelial nuclear proteins to be minor (approximately 20%) with sequencing sensitivity of one pmol. These studies extend our on-going efforts toward the establishment of computerized database of rat liver epithelial cellular proteins (Wirth et al., Electrophoresis, 1991, 12, 931-954) to aid in the delineation of polypeptides critically involved in cellular growth and differentiation as well as transformation.

Abstract
Fourteen human lung tumors of various histopathological types were subjected to two-dimensional gel electrophoresis (2-DE). Samples were prepared for 2-DE using a nonenzymatic sample preparation (NESP) technique recently established in our laboratory. Variations in the expression of some polypeptides were observed between tumors of different histopathological types. To this end, high expression of beta-tubulin, heat shock proteins 73 and 90, lamin B, and proliferating cell nuclear antigen (PCNA) were observed in small cell lung carcinomas (SCLC). One polypeptide of unknown identity (35 kDa, pI 5.5) was significantly overexpressed in primary lung adenocarcinomas compared with SCLC, squamous cell lung carcinomas, metastatic lung adenocarcinomas from colon and rectum, and normal tissue. The amino acid composition of this polypeptide is presented. In summary, combining the NESP technique and 2-DE is an effective approach to define tumor-specific markers.

Abstract
The master two-dimensional computer database of rat liver epithelial (RLE) cellular proteins (Wirth et al., Electrophoresis 1991, 12, 931-954) has been expanded to include detailed information concerning 1100 nucleoplasmic (cytosolic) and 850 particulate associated [35S]methionine labeled as well as 215 nucleoplasmic and 269 particulate associated [32P]orthophosphate labeled RLE nuclear polypeptides, respectively. The RLE nuclear protein database developed using the Elsie 5 gel analysis system contains both qualitative and quantitative annotations including polypeptide identification number, protein name (if known), molecular weight and pI information, quantitation and polypeptide spot shape, subcellular location, as well as specific information regarding transformation (chemical and spontaneous) and growth-related characteristics. Microsequencing of polypeptides directly from two-dimensional (2-D) blotted membranes has recently been established in our laboratory and provides a highly efficient and rapid means of polypeptide identification in the absence of specific antibodies. At present the RLE protein database is still in the developmental stage and is continually being updated as additional information is obtained. Nonetheless, it is anticipated that knowledge obtained concerning the identification and characterization of specific transformation and/or growth regulatory proteins in the RLE in vitro cell system will not only have direct application to other rodent and human 2-D protein databases currently under development but will also complement them.

Abstract
Two-dimensional polyacrylamide gel electrophoresis (2-D PAGE) analysis of silver stained polypeptides was used to discriminate the cell protein profiles in chronic B cell malignancies. We identified 5 distinct polypeptides (H1 to H5) present in hairy cell leukemia (HCL) (14 cases) and absent in most chronic lymphocytic leukemia (CLL) and normal B lymphocytes. Two polypeptides, H2 and H5, were absolutely specific of HCL. The 2-D PAGE profiles found in 3 splenic lymphoma with villous lymphocytes (SLVL) and 2 HCL variants (HCL-V) were similar to HCL with a unique additional peptide present in 3/3 SLVL and 1/2 HCL-V. When HCL and SLVL were assessed for the CLL stage-specific 2-D PAGE patterns, HCL was related to stage A/B while SLVL was related to stage C. In conclusion, 2-D PAGE analysis of the molecular pattern of B lymphocytes provides a new means to recognize the leukemic origin of the sample and distinguish HCL from CLL and SLVL.

Abstract
OBJECTIVE Antigen-specific CD4+ T cells treated with DNA methylation inhibitors become autoreactive, suggesting a novel mechanism for autoimmunity. To test whether this mechanism might be involved in systemic lupus erythematosus (SLE), phenotypic markers for the autoreactive cells were sought. METHODS Cloned normal T cells were treated with the DNA methylation inhibitor 5-azacytidine (5-azaC) and studied for altered gene expression. T cells from patients with active SLE were then studied for a similar change in gene expression, and cells expressing the marker were tested for autoreactivity. RESULTS 5-azaC-treated normal T cells had increased CD11a (leukocyte function-associated antigen 1 alpha) expression relative to other membrane molecules. A T cell subset with similar CD11a expression was found in patients with active SLE. This subset contained cells that spontaneously lysed autologous macrophages, with a specificity similar to that of 5-azaC-treated cells.

Abstract
State-of-the-art and future perspectives are discussed for the application of two-dimensional protein maps to basic medical research and routine clinical chemistry problems. Despite the technical advances that allow effective processing of a large number of samples and the refinement of devices and procedures for image analysis, at present two-dimensional maps are mostly confined to research purposes, i.e. to the inventory of normal constituents of body fluids and tissues on the one hand, and to qualitative-quantitative alterations of some protein spots in a number of instances (genetic, degenerative, infectious or xenobiotic diseases) on the other. It is hoped that in some instances a single primarily affected component will be able to be identified and then specifically tested (for instance by immunological means) as a diagnostic marker, but complex pathological patterns would still require the analysis of a large number of peptides at the resolution level only afforded by two dimensions. Further simplification of the protocols, for example with ready-made gels, and data reduction systems might then allow the application of the technique to be extended to general clinical laboratories.

Abstract
A high-resolution two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) was used for total cellular polypeptide mapping of two established lymphoma cell lines; MANCA, a Burkitt's line representing a high grade lymphoma (HGL) and WSU-NHL (nodular histiocytic lymphoma) representing an intermediate grade lymphoma (IGL). Gels were digitized and analysed with an image scanning computer using the Elsie 4 system. Polypeptide mapping revealed striking similarities in 1100 polypeptide spots in both types. However, three polypeptides were unique to HGL (Molecular mass/isoelectric point (Mr/PI): 39/4.4, 35/5.6, 33/4.8), and one to IGL (95/4.7). In order to investigate the kinetics of expression of these polypeptides, the two cell lines were treated with two protein kinase C (PKC) activators, tumour promoting 12-O tetradecanoylphorbol 13-acetate (TPA) and bryostatin 1. 2D-PAGE of the treated cells revealed that the HGL line loses its unique polypeptides and expresses a new one. The new polypeptide has the same Mr and PI as that unique to the untreated IGL (95/4.7). TPA or bryostatin 1 treatment of the IGL line for 72 h induced no significant changes. Our data show a unidirectional change from HGL to IGL, supporting the clinical notion that HGL is less differentiated than IGL. It also shows the similarity in the mode of action of bryostatin 1 and TPA in inducing these polypeptide changes.

Abstract
By direct analysis of the polypeptide constituents of leukemic cells, we have previously detected several polypeptides that are restricted in their expression to acute lymphoblastic leukemia (ALL). In this study, we provide evidence that two polypeptides designated L2 and L4 are structurally related and represent novel markers for common ALL. Partial amino acid sequence analysis did not uncover differences between L2 and L4. The sequences obtained correspond to a previously cloned human gene designated hsp 27 that is expressed, following heat shock treatment, in a variety of cells. 32Pi incorporation studies indicate that L4 is an unphosphorylated form and L2 is a phosphorylated form of hsp27. The two forms were inducible by heat shock in leukemic and nonleukemic lymphoid cells. Thus, in acute leukemia, the common ALL subtype is uniquely characterized by the constitutive expression of a polypeptide that represents a major cellular phosphoprotein.

Abstract
During the last decade several strategies have been developed to identify proteins which could serve as markers in tumor biology. One avenue of great promise to detect such proteins seems to be the separation of prefractionated organelles from tumor cells by high resolution two-dimensional electrophoresis. Using detergent-lysed nuclei from several human tumor cell lines, especially from brain tumors, and two-dimensional electrophoresis, we analyzed the nuclear protein pattern obtained after sequential salt extraction of tumor cell nuclei. In addition to proteins occurring in all tumor cell lines, the pattern of different tumor cell lines exhibits considerable differences when proteins were visualized by silver staining, thus emphasizing the specificity of nuclear proteins with respect to the cell type. Even quantitative variations of the nuclear phosphoproteins 23/4 were detectable, indicating a potential correlation between their synthesis/phosphorylation and the proliferation behavior of tumor cells. The data indicate that nuclear proteins with their distinct heterogeneity and tissue specificity may represent a powerful source in determining tumor-specific proteins. The extent of chromosomal protein heterogeneity may be additionally increased by their covalent modification by nuclear kinases; therefore, tumor-specific nuclear proteins may occur as quantitative and qualitative variations.

Abstract
There is substantial evidence that the haematopoietic microenvironment is crucial to the growth and differentiation of haematopoietic cells. This microenvironment is composed of stromal cells, soluble factors and extracellular matrix (ECM). We have shown that a complex extract of bone marrow ECM can stimulate the growth and differentiation of haematopoietic cells in vitro. Furthermore, the use of inhibitors or stimulators of ECM synthesis in long-term marrow culture affects cell proliferation. On a molecular level, however, the interactions between ECM and haematopoietic cells are not well understood. We have investigated the adhesion between specific bone marrow ECM components and haematopoietic cells, and found a protein, 'haemonectin', of relative molecular mass 60,000 in bone marrow ECM which is a lineage- and organ-specific attachment molecule for cells of granulocyte lineage. This specificity distinguishes haemonectin from previously described adhesion proteins which have a wider tissue distribution and cell type specificity.
